<h2>Graph2d | Dynamic Styling Example</h2>

<div style="width:800px; font-size:14px; text-align: justify;">
    This example shows how to programmatically change the styling of a group. While this can also
    be done in CSS, this must be statically defined, and the programmatic interface allows the
    user to define the look of the graph at runtime.
